Hi folks.
First a disclaimer: I'm omitting a lot of information, because there is hardly any limit to what I could include.
Instead, I'll mention what seems most important, then dialog if anyone shows an interest.
The objective: convert an existing private java library from ddxq to BaseX.
I am using these libraries, all coming to me via BaseX (I think):
[cid:image002.jpg@01D50A5D.04478550]
My intention is to use the local option ... this library is already running in the server (or in Eclipse).
import net.xqj.basex.local.BaseXXQDataSource;
Here's my connection code (actually a constructor method):
public XQTransformer (String xqueryName) throws Exception { String queryPath = String.format(filePath, xqueryName); URI queryUri = new URI(queryPath); FileReader xqueryReader = new FileReader(new File(queryUri)); xqds = new BaseXXQDataSource(); //xqds.setOptions("serialize=indent=yes"); //xqds.setBaseUri(queryPath); xqconnection = xqds.getConnection(); XQStaticContext context = xqconnection.getStaticContext(); context.setBindingMode(XQConstants.BINDING_MODE_IMMEDIATE); xqconnection.setStaticContext(context); xqpe = xqconnection.prepareExpression(xqueryReader); }
setBaseUri is for references from the xQuery to helper files in the same directory. Later I compensate by overriding the current user directory.
But I am throwing an Exception here:
while (!rs.isClosed() && rs.next()) {
java.lang.NullPointerException at org.basex.query.QueryContext.next(QueryContext.java:353) at org.basex.query.expr.gflwor.GFLWOR$1.next(GFLWOR.java:64) at org.basex.query.QueryContext.next(QueryContext.java:353) at org.basex.query.scope.MainModule$1.next(MainModule.java:101) at net.xqj.basex.bin.h.b(Unknown Source) at net.xqj.basex.bin.r.a(Unknown Source) at net.xqj.basex.bin.bL.next(Unknown Source) at net.xqj.basex.bin.bR.next(Unknown Source) at com.emc.metlife.util.xql.XqueryTransformation.xmlFormatted(XqueryTransformation.java:89) at com.emc.metlife.util.xql.XqueryTransformation.getTransformedData(XqueryTransformation.java:194) at com.emc.metlife.util.xql.XqueryPooledTester.test(XqueryPooledTester.java:58) at com.emc.metlife.util.xql.XqueryPooledTester.main(XqueryPooledTester.java:43)
The particular xquery file is working for me in the BaseX GUI.
Thanks!
